Tutorials descriptions

 

1. Preparation and characterization of cellulosic nanomaterials (2 hours)
Conveners: Dr inż. Roksana Markiewicz, Dr Patryk Florczak, Dr Marcin Jarek
Duration: 2h
Number of attendees (per one group):
Description: In recent years, a wider application of biopolymers has been proposed at the nanostructure level for the development of variety of biocompatible products. The natural-derived polymers are renewable, non-toxic, biodegradable and in general environmental friendly materials, possessing excellent functional properties. Among these natural products, it is worth mentioning the great abundance of the polysaccharides, which are considered the most plentiful biomolecules in nature. The main importance of this kind of biopolymers is the fact, that a lot of them can be derived from the agricultural waste. Nanocellulose has gained increasing interest for a wide range of applications relevant to the fields of materials science an d biomedical engineering due to its renewable nature, anisotropic shape, excellent mechanical properties, good biocompatibility, tailorable surface chemistry, and interesting optical properties[1-3].
This tutorial will be generally divided into two sections: (1) Preparation of cellulose nanofibers with the use of various methods and (2) its characterization (IR and XRD). During the tutorial one will find out about cellulose and other natural polymers, cellulose derivatives, cellulose based nanomaterials, methods of their preparation, functionalization, characterization and possibilities of use. Young scientists will take part in the preparation process in NanoBioMedical Centre’s Chemical Laboratory, Moreover, they will take part in the evaluation of their crystal structure based on the Powder XRD measurements - WAXS (Wide-angle X-ray scattering). In general Powder XRD technique allows to identify the structure by comparison with a standard catagorized diffractograms of known phases or described in the literature. Diffraction pattern is a specific characteristic fingerprint for a given structure. Measurements will be performed by powder technique on Empyrean (PANalytical) diffractometer (CuKα radiation) located in NanoBioMedical Centre. Moreover the ICDD PDF-4 + 2019 database will be used for precise characteristics of obtained materials.

2. Focused Ion Beam
Conveners: Dr Karol Załęski
Duration: 2h
Number of attendees (per one group): 3
Description: A practical introduction into the FIB technique will be introduced on the examples of cross-section preparation for Scanning Electron Microscopy imaging.

3. Studying the chemical composition of nanomaterials using X-ray photoelectron spectroscopy (XPS)
Conveners: Dr Mikołaj Lewandowski
Duration: 2h
Number of attendees (per one group): 3-5
Description: The aim of the tutorial is to introduce the participants to the basics of X-ray photoelectron spectroscopy (XPS) - a powerful technique that allows studying the chemical composition of nanomaterials. The participants will gain knowledge on the physical principles of the method, instrumental details, proper sample preparation for ultra-high vacuum (UHV) studies, setting up XPS measurements and performing results analysis and interpretation.

Duration: 2h
Number of attendees (per one group): 4
Description: In this tutorial the basic use of confocal laser scanning microscope for biological samples will be presented. In order to visualize the nanoparticles internalization, human cells will be co-localized with specific cellular ultrastructures, then nanoparticles localization as well as impact on cellular morphology will be analyzed.

Conveners: Dr Tomasz Zalewski
Duration: 2h
Number of attendees (per one group): 4
Description: The aim of the tutorial is to introduce the basics of procedures in the MRI lab. During classes images of biological objects with a well-defined structure will be obtained, using Fourier imaging methods with spin-echo and gradient echo sequences.

6. Thermoresponsive hydrogels - volume phase transition kinetics observed via NMR
Conveners: Dr Jacek Jenczyk
Duration: 2h
Number of attendees (per one group): 4
Description: Hydrogel swelling-deswelling kinetics is studied using variable-temperature time-laps NMR experiment which enables monitoring hydration-dehydration processes at the molecular level. There are two independent phenomena observed during polymer network collapse namely; a) chemical shift variation, and b) NMR signal intensity variation. The first mechanism reveals inequivalent chemical environment of hydrated and dehydrated state and clearly indicates a gradual deshielding of methyl protons above LCST. The second mechanism, concerning NMR signal amplitude variation, contributes to gradual polymer network stiffening above LCST. In the collapsed state the hydrogel resembles solid-like material characterized by significantly reduced polymer dynamics.

7. Host-guest complex exploration by the use of NMR spectroscopy
Conveners: Dr hab. Kosma Szutkowski, Dr Łukasz Popenda, Adam Klimaszyk
Duration: 2h
Number of attendees (per one group): two simultaneous groups - 3 person per group
Description: The workshop is dedicated to young scientists who are interested in diverse applications of NMR spectroscopy. In this particular workshop we will cover host-guest interactions by 1H NMR spectroscopy (chemical shifts) and NMR diffusometry. During the workshop we will exploit well known cyclodextrin inclusion complex. The confirmation of the complex formation will be demonstrated by two independent methods. Some basic understanding of NMR phenomenon is desirable.

8. NanoIndentation

Duration: 2h
Number of attendees (per one group): 4
Description: In this tutorial, the basic concepts of nanoindentation will be introduced. Concepts such as young modulus and hardness will be explained in the frame of nanomaterials and nanotechnology applications. Direct contact with the instrument and general demonstration of the capabilities of the system is expected. The hands-on tutorial will include: measuring the elastic modulus of different materials, interpretation of Load vs Displacement data by the Oliver-Pharr method, introduction to nanotribology and nano Dynamical Mechanical Analysis.

9. Imaging of nanomaterials by means of electron microscopy methods

Duration: 2 h
Number of attendees (per one group): 6
Description: The main aim of this tutorial is to present how deep we are able to take an insight into complex nanostructures ranging from soft to solid matters. Over the time of two hours participants will have chance to prepare samples as well as analyze materials using scanning or high resolution transmission electron microscope in CNBM Electron Microscopy Laboratory (http://cnbm.amu.edu.pl/en/electron-microscopy). We will explore atomic structure of materials at level of Angstroms and investigate their elemental composition.
